Perhaps you should try some spelling variations:
"heir apparent" » "huir apparent", "her apparent", "hair apparent", "heir aparente", "heir apaparente", "heir apparental"
"heir aparentalalely" » "huir aparentalalely", "her aparentalalely", "hair aparentalalely", "heir aaparentealalely", "heir aparentalalalely"
"heir parent" » "huir parent", "her parent", "hair parent", "heir aparente", "heir parental"
"weir apparently" » "weir aparentely", "weis apparently", "wei apparently", "weil apparently", "weir apaparentely", "weir apparentally"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("heir apparent") OR ("weir apparently"))) OR ("heir aparentalalely"))) OR ("heir parent"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"heir apparent\") OR (\"weir apparently\"))) OR (\"heir aparentalalely\"))) OR (\"heir parent\"))*".
• Removing quotes may allow a broader search: (((((( heir apparent ) OR ( weir apparently ))) OR ( heir aparentalalely ))) OR ( heir parent ))*.
